The concept is simple - and it's a good one:
LTE (4G) network signals can only handle data, not calls or texts, so customers have to rely on a decent 3G signal to be able to make and receive calls and texts.
Three's 4G Super Voice aims to provide VOIP-like calling and texting, much like WiFi calling and messaging.
4G signals are also better at penetrating buildings and covering wider areas than 3G signals, so this technology should be able to provide improved voice, text and data coverage inside buildings and in rural areas. These are two areas where the Three network really struggles.
Three have said that they aim to be able to provide this service so that "customers in rural areas can receive better mobile services".
All of this is great, apart from the fact that Three really have screwed up with their marketing.
Firstly, "4G Super Voice" is only available to Three customers using a Samsung Galaxy S5 or LG G4 - Not even S6 owners get an opportunity to improve their network.
Three have stated that the iPhone 6/6 Plus, the HTC One M9, plus some other (not yet specified) handsets will also be able to make use of 4G Super Voice later this year.
- Not exactly "rural" areas, Three?
It's good to see that this technology is being used, but like all networks, Three are rolling out the best bits to the most subscribers, with marginal and rural areas losing out on getting decent signals yet again.
I live within easy reach of three major towns and a three cities, yet 4G on Three is a myth, apart from in the very centre of two of these town and the cities. Rural areas in-between can just about get a 3G data connection, and calls/texts are unreliable.
Within cities and towns with 4G coverage, this service will be welcomed by some, and remain cryptic for most.
Three's "4G Super Voice" is a step in the right direction, but I believe that it will be many years before it really starts to benefit anyone in rural areas (if Three even bother to improve out of town coverage at all).
